"Stuck with" is a colloquialism. It's just saying that she'd planned to make X profit and instead will end up with a loss. There's plenty of ways to make a loss: sell it at a discount (near or below what you bought for) or spend so much effort making sales that your opportunity cost is more than your profit.
